Browser-first by design.
The candle, Halloween candy, Christmas lights, yarn, payday, and DPI calculations run locally in your browser. If you save an actual Halloween turnout count or a payday plan, that data is stored in this browser's local storage.
PDF tools
The online PDF editor, merge, split/extract, compression, PDF-to-JPG, images-to-PDF, watermark, page-number, crop, binding-margin, booklet/signature, bleed/crop-mark, and shipping-label tools process selected files in the browser. This code does not require uploading those files to a Quicklio server.
Image and social tools
Exact-KB resizing, passport/ID photo sizing, line-art conversion, the online image editor, contact sheets, poster tiling, Instagram fitting, and pumpkin stencils process selected images locally in the browser to create previews and downloadable output.
Barcode and QR labels
Pasted or uploaded CSV data is parsed in your browser and used to generate label sheets locally; Quicklio does not need a server upload for this workflow.
Analytics and consent
Quicklio uses Google Analytics 4 to understand visits, traffic sources, page usage, and engagement only after you choose Accept analytics. Until then, the Google Analytics tag is not loaded. Advertising storage, ad user data, and ad personalization remain disabled.
Your analytics choice is stored in this browser so Quicklio can remember it. You can reopen the choice at any time using Privacy choices in the footer. If you accept, Google may process technical and usage information under its own privacy terms. Google Privacy Policy.
PDF compression
Quicklio's compression mode rasterizes pages locally in the browser. This can remove selectable text, form fields, links, and some vector detail from the downloaded result.
